SLAG-CAR.

SPECIFICATION forming part of Letters Patent No. 474,228, dated May 3, 1892.

Application filed August 20, 1890. Serial No. 362,512. (No model.)

To @ZZ whom it may concern:

Be it known that I, SIMON B. DEXTER, of Glendale, in the county of Beaver Head and State of Montana, have invented a new and Improved Slag-Oar, of which the followingis a specilication, reference being had to the annexed drawings, forming a part thereof, in which- Figure l is a side elevation, partly in section, of my improved slag-car. Fig. 2 is a vertical transverse section taken on line 2 2 in Fig. l, and Fig. 3 is a detail side elevation of the catch for holding the car in an elevated position.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to provide a slag-car for use in connection with my improved lore-roasting furnace, described in my application, Serial No. 287,374, filed October 6,1588.

My improved car is designed to be used in connection with anelevator, by rneansof which the track upon which it stands and the car are moved upward until the car sides and ends come into contact with the bottom of the furnace.

My invention consists n the combination, with the car-body, of spring-supported sides and ends adapted to contact with the bottom of the furnace as the car is elevated. The invention also further consists in locking-levers for holding the car securely in a central position.

The wheels a are attached to the axles A A' and adapted to run on the track-rails l). To the axles are litted the yokes B B', the said axles being capable of turning in the yokes, and the upper portions of the yokes are slotted longitudinally to receive the ears C of the bolsters D D', which are attached to the car-body F. A rod G passes through apertures in the yokes and in the ears and forms a pivot for the car-bod y. Between ears c, projecting from the rear yoke B', is pivoted the angled lever II, the shorter arm of which prou jects through a hole in the yoke and is capable of entering a recess in the ear C of the bolster D', so as to hold the car-body in a horizontal position. A spring d, attached to ends c, and which are oppositely arranged '5 5 with respect to each other. The longer arms of the levers I I' project beyond the ends of the car-body and are beveled in opposite directions, as shown. The slag-cars travel on a circular track, so that when an empty car 6o approaches a filled car the engagement of the lever I of the full car by the lever I' of the empty car tilts the lever I of the filled car, thus releasing it, allowing it to pass 0n by its own gravity, the track being inclined to ad- 6 5 mit of this action. The empty car follows the full car and takes its place under the furnace, where it is locked by the levers I I', as before described.

To the car-body are attached the cylindri- 7o cal supports J, which are slotted longitudinally to receive the side and end pieces K and K. Each su pportJ is furnished with a flange f at its lower end, upon which rests a spiral spring g, the said spiral spring g being suflicient to support the side and end pieces K and K in an elevated position when the said side and end pieces are not subjected to any pressure; but when the car is moved into its position underneath the furnace and then 8o raised the side and end pieces K Ii' yield, but are held in close contact with the bottom of the furnace by the springs g.

In the center of the platform by which the car is supported underneath the furnace is arranged a stop L, having beveled sides adapted to fit in the space between the sector-shaped ends c of the levers I I. As the oar is moved forward underneath the furnace-in the direction indicated by the arrow, 9o

for examplethe sector-shaped end e of the lever I will engage the stop L and be elevated thereby, and willY by its own gravity fall in behind the stop as soon as the sector-shaped end cof the lever I strikes the stop. By this arrangement the car will be held in a central positionuponitssupport. Afterthecaris filled the long arm of the lever I is pressed down, disengaging the sector-shaped end c from the stop L, thus allowing the car to pass along in roo the same direction, When its place Will be filled by another car.

To facilitate the dumping of the car, one or both of its sides is provided with an eye 71A for receiving a lever. .The floor of the car is provided with a lining Mof fire-brick for pro-V the having yokes and the car-body having trans-` verse bolsters on its lower side provided with ears pivoted to theyoketd'permit the body to dump laterally, one offthe earshavinga recess, ofe `a longitudin'ally-extending" anglelever Hjpivo'te'd 'to-fone of theyokes,-With its innerV ed'engaging said ec'ess to lock the bodyjsnbstantally4 as setfortha f r "25 Thefcornbination, with a slagcar, 'of-'the lockinglevers II and the stop L, substantially as specified.

The combination, with the car-body F, of the slotted cylindrical supports J, the springs g, and the movable side and end pieces K and K', substantially as specified. 5 The combination, with the car, of the longitndinally-extending levers I I', pivoted between their ends beneath the car, with their outer ends projecting beyond the ends of the car, the inner ends of the said levers being spaced apart and projected downward to engage a track projection and lock the car, substantially as s'liownanddescribed. l
